Fully supported Linux + proper suspend-to-RAM are the two things I want out of Apple Silicon and may never quite get. Better online low power states are fine, but I want suspend-to-RAM and suspend-then-hibernate.
If I close my laptop for a few days, I don't want significant battery drain. If I don't use it for two weeks, I want it to still have life left. And I don't want to write tens of gigabytes to disk every time I close the lid, either!
What happens if you enable airplane mode before closing the laptop? That should power down all radios so battery drain should be approximately equivalent to S3 standby.
